This invention relates to improvements in weather seals for doors, windows or any other type of closure where a seal is desired.

It is one of the principal objects of the invention to provide a seal of this character which is of simple, eflicient, durable and inexpensive con struction and positive in its operation of sealing off any space between doors, windows, and the like, and their respective thresholds or frames.

A still further object is the provision of a seal of this character which offers no resistance to the opening and closing movements of the doors or windows to which it is applied.

A still further object resides in the ease of combining the seal with weather stripping already installed or forming the seal as an integral part of the weather stripping.

These and other objects will appear as my invention is more fully hereinafter described in the following specification, illustrated in the accompanying drawing and finally pointed out in the appended claim.

In the drawing:

Figure 1 is a fragmentary front elevation of a door and frame showing a seal made in accordance with my invention applied to the bottom edge of the door.

Figure 2 is an enlarged sectional end elevation taken along the line 2-2 of Figure 1.

Figures 3, 4 and 5 are views similar to Figure 2 illustrating modified forms of the invention.

Referring now more particularly to the drawmg:

In Figure 1, reference numeral 1 indicates, gen erally, a door mounted in the conventional manner within a frame 2 having the usual sill 3 across its bottom end and upon which is mounted the usual threshold 4.

In Figure 2 I have shown the bottom edge of the door provided with the usual weather stripping 5 turned back on itself as at 6 for engagement with one edge of a weather-strip cap I secured to the threshold in the usual manner.

My new and improved seal comprises a strip 3 of any suitable flexible material, such as rubber, or the like, extending entirely across and dependingfrom the bottom edge of the door. The seal is secured along its upper edge to metallic strip 9 also extending, entirely across the door and secured to the front face thereof by nails, screws or other suitable fastening elements as indicated at If). The lower portion of the strip 9 is folded upwardly as at ll then downwardly as at 12 to receive the top edge of the seal. By compressing these folded portions of the strip 9 the seal becomes permanently secured to the strip.

The height of the seal 8 is normally greater than the distance between the bottom edge of the folded portions of the strip 9 and the threshold so that the bottom edge of the seal will frictionally engage the top surface of the threshold when the door closed, as shown. Also, when in this position, the bottom edge of the seal will be forced against the outside and downwardly turned edge !3 of the weather-strip cap 'l by any wind pressure against the seal from the exterior thereof.

In certain installations where a weather-strip cap 1 and the co-operating weather stripping 5 are not used I extend the seal to a reater depth and provide an abutment for it lower edge by routing out the top surface of the threshold 4 as indicated at it in dotted lines to provide a shoulder 5 against which the bottom edge of the seal bears when the door is closed and particularly when any outside wind pressure is applied against In the modified form of the invention illustrated in Figure 3 I form the metallic strip 9A and the weather stripping 5A out of a single strip of material into vertical and horizontal portions as shown and secured as at [0A and It to the front and to the bottom, respectively, of the door.

In Figure 4, I have illustrated the manner in which the seal is attached to the bottom edge of the door in a less conspicuous manner than that shown in Figures 2 and 3. To accomplish this I turn the upper portion of the metallic strip 913 at right angles to itself and attach it, as at ll, to the horizontal surface it of the undercut portion of the bottom edge of the door.

In the further modified form shown in Figure 5, the seal 8A, instead of being of single thickness, is doubled back on itself into tubular form, as shown, and is readily yieldable into conformity with the surface of the threshold or any abutment or weather-strip cap applied thereto for effecting the seal. It may also be applied entirely around a frame for contact with a door or window when moved into a closed position, instead of being applied to the bottom edge of a door only.

While I have shown a particular form of embodiment of my invention, I am aware that many minor changes therein will readily suggest themselves to others skilled in the art without departing from the spirit and scope of the invention. Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:

A weather seal for space between a closure and a frame element thereof, comprising in combina-- tion a weather-strip cap secured to and extending entirely across the frame element, said cap having a horizontally flanged rear marginal portion and a downwardly turned forward marginal portion, a fastening strip having a vertical portion secured across the lower front face of the closure and an integral horizontal portion secured to the bottom edge of the closure, said vertical portion being doubled and redoubled on itself, a strip of flexible material secured to said vertical portion between the said doubled portions thereof and extending downwardly therefrom into contact with said frame element, and the rear marginal edge of the horizontal portion of said fastening strip being doubled under on itself for engagement with the horizontally flanged rear marginal portion of said weather-strip cap.
